The headless-browser source is getting a bit unwieldy. The ordering of
class and method definitions is fragile; e.g. the application and web
view classes each require full definitions of each other. So it has
reached the point where it makes sense to give headless-browser some
better file structure.
To prepare for that, this patch simply moves its source to live along-
side the other browser chromes. This location is a bit better prepared
for creating more files, as the Utilities folder doesn't even have its
own CMakeLists.txt.
This allows us to get identical metrics on macOS and Linux. Without
this, Skia will use CoreText on macOS and give us slightly different
text metrics. That causes layout tests to be slightly different on
different platforms, which is a huge headache. So let's not do that.
You can now launch Ladybird and headless-browser with --force-fontconfig
to load fonts through fontconfig. Tests run in this mode by default.
The identifier "Protocol" is claimed by Objective-C and Swift for use
by the language's built-in protocol conformance feature, which is
similar to Rust traits or Java interfaces.
Rename LibProtocol -> LibRequests, and its namespace from Protocol to
Requests to accomodate this.
Currently, if we want to add a new e.g. WebContent command line option,
we have to add it to all of Qt, AppKit, and headless-browser. (Or worse,
we only add it to one of these, and we have feature disparity).
To prevent this, this moves command line flags to WebView::Application.
The flags are assigned to ChromeOptions and WebContentOptions structs.
Each chrome can still add its platform-specific options; for example,
the Qt chrome has a flag to enable Qt networking.
There should be no behavior change here, other than that AppKit will now
support command line flags that were previously only supported by Qt.
This allows developers on macOS to open Ladybird.app in Instruments.
Add some documentation for how to use the command as well. It is enabled
automatically when CMAKE_BUILD_TYPE is not Release or RelWithDebInfo.
For some reason, moving the UI-specific CMake to its own files prevents
resource files from being copied to the Resource directory in the macOS
application. I'm not sure what the difference here is, but doing this
step during create_ladybird_bundle() works.
We already have required this version for quite a while for Lagom,
Ladybird and Serenity. Now that we require it in all of our CMakeLists,
let's scrub for better ways of writing things.
It previously resided in LibWebView to hide the details of launching a
singleton process. That functionality now lives in LibCore. By moving
this to Ladybird, we will be able to register the process with the task
manager.
On macOS, it's not trivial to get a Mach task port for your children.
This implementation registers the chrome process as a well-known
service with launchd based on its pid, and lets each child process
send over a reference to its mach_task_self() back to the chrome.
We'll need this Mach task port right to get process statistics.
This implementation uses a really basic WebView to update stats once
a second. In the future it might make more sense to both move the
details into LibWebView, and to create a native widget for each platform
to remove the overhead of having an extra WebView.
This URL library ends up being a relatively fundamental base library of
the system, as LibCore depends on LibURL.
This change has two main benefits:
* Moving AK back more towards being an agnostic library that can
be used between the kernel and userspace. URL has never really fit
that description - and is not used in the kernel.
* URL _should_ depend on LibUnicode, as it needs punnycode support.
However, it's not really possible to do this inside of AK as it can't
depend on any external library. This change brings us a little closer
to being able to do that, but unfortunately we aren't there quite
yet, as the code generators depend on LibCore.
These are standalone applications meant to be run by the user directly,
as opposed to other libexec processes which are programmatically forked
by the browser. To do this, we simply remove these processes from the
`ladybird_helper_processes` list. We must also explicitly list the
dependencies for these processes.
For Ninja Multi-Config, Xcode and Visual Studio, the way we set up our
output directories would result in exectuables that can't run from the
build directory. Add the same sauce that we added to Jakt to insert
``$<CONFIG>`` where appropriate.
After ea682207d0, we need Userland/
included directly in these application executables. This only impacts
the build with Ladybird/CMakeLists.txt as the top level CMakeLists, as
the Lagom/ directory includes Userland/ globally.
It aligns better with the Filesystem Heirarchy Standard[1] to put our
program-specific helper programs that are not intended to be executed by
the user of the application in $prefix/libexec or in whatever the
packager sets as the CMake equivalent. Namely, on Debian systems this
should be /usr/lib/Ladybird or similar.

Don't put them in bin/ and then copy them to the bundle dir later, as
this means that they only get updated in the bundle directory if the
Ladybird binary itself needs updated. Which is not a fun workflow if you
are working on WPT and want to hack on the WebDriver binary.
